When The Cookie Meets The Blockchain
by Lawrence D'Oliveiro 17 Aug '17

17 Aug '17

Cryptocurrencies like Bitcoin are supposed to allow for completely anonymous financial transactions. However, if you use them at an online shopping site, such places often have enough tracking information in place to link you to a particular currency transaction anyway. <http://freedom-to-tinker.com/2017/08/17/when-the-cookie-meets-the-blockchai…>

Learn the basics of the ZSH shell
by Peter Reutemann 17 Aug '17

'Bash isn't bad. It gets the job done just fine, but have you ever considered what it'd be like if Bash had some extra features to make it more convenient to work with? That's more-or-less what ZSH is. It includes all of the features that you'd expect from Bash, but it also has some really nice additions to make your life easier. Actually, you'll be amazed at how much easier they make working in the command line.

How to secure your LAMP server
by Peter Reutemann 17 Aug '17

17 Aug '17

'The LAMP stack which stands for Linux, Apache, MySQL/MariaDB and PHP/Python/Perl is a very popular combination of free and open-source software used to run millions of websites today. Although many opt for the much efficient LEMP stack based on Nginx instead of Apache, there are still a significant number of users that choose LAMP for their projects. In fact, more than 30% of the active websites today run on top of LAMP. The stack is considered as reliable and very suitable for running high-performance high-availability web applications. In this tutorial we are going to show you how to secure the LAMP stack on your Linux VPS.' -- source: https://www.rosehosting.com/blog/how-to-secure-your-lamp-server/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Email Provider ProtonMail Says It Hacked Back, Then Walks Claim Back
by Peter Reutemann 17 Aug '17

17 Aug '17

'On Wednesday, encrypted email provider ProtonMail claimed it had hacked someone who was impersonating its service in phishing emails, and the company then swiftly deleted the tweet. Early Wednesday morning, the security researcher known as x0rz tweeted out a series of screenshots allegedly showing someone sending emails that directed targets to a fake ProtonMail login screen. "You have an overdue invoice," the message read. In response, ProtonMail said it had taken action. "We also hacked the phishing site so the link is down now," ProtonMail tweeted. Depending on the context and what exactly the retaliating organization did, hacking back can be illegal. Hacking could violate the Computer Fraud and Abuse Act, or perhaps even wiretapping legislation. A recently proposed bill would attempt to legalize the practice. ProtonMail swiftly deleted its tweet, but not before x0rz could grab and subsequently tweet a screenshot. x0rz then deleted his own tweet at the request of ProtonMail.' -- source: https://it.slashdot.org/story/17/08/16/2021257/email-provider-protonmail-sa… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Review: System76’s Galago Pro solves “just works” Linux’s Goldilocks problem
by Peter Reutemann 16 Aug '17

16 Aug '17

'In recent years, the PC industry has finally spawned a few manufacturers offering up machines with Linux pre-installed to eliminate this issue. By this point, I've tested most of them around Ars: Dell's XPS and Precision lines both have Linux-friendly offerings, and dedicated Linux manufacturers like System76 have long offered decent hardware with Linux pre-installed. In all this testing, I've yet to encounter a driver problem, which is the real benefit of a machine with Linux pre-installed. (Though to be fair, I could say the same for the Lenovo x240 that serves as my daily driver.) Still, finding the perfect Linux laptop has always been and remains something of a Goldilocks problem: this one is too big, this one is too underpowered, this one has too little RAM, this one lacks a big SSD, and so on. Generally speaking, if you want power and storage you're going to end up with something too big to comfortably throw in a bag and carry all day. The Dell Precision 7520 and the System76 Oryx Pro are good examples of this. [...] What Linux users like myself have long wanted is a laptop with roughly the form factor and weight of a Macbook pro, but with the option to get 32GB of RAM or 3TB of storage. This is the mythical unicorn of pre-built Linux machines, a laptop that is both reasonably lightweight and powerful. And that, my fellow Linux users, is refreshingly what System76 has managed to deliver with its new Galago Pro laptop.' -- source: https://arstechnica.com/gadgets/2017/08/review-system76s-galago-pro-solves-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OpenSource.com Test-Drives Linux Distros From 1993 To 2003
by Peter Reutemann 14 Aug '17

14 Aug '17

'A unique trait of open source is that it's never truly EOL (End of Life). The disc images mostly remain online, and their licenses don't expire, so going back and installing an old version of Linux in a virtual machine and getting a precise picture of what progress Linux has made over the years is relatively simple... Whether you're new to Linux, or whether you're such an old hand that most of these screenshots have been more biographical than historical, it's good to be able to look back at how one of the largest open source projects in the world has developed. More importantly, it's exciting to think of where Linux is headed and how we can all be a part of that, starting now, and for years to come. The article looks at seven distros -- Slackware 1.01 (1993), Debian 0.91 (1994), Jurix/S.u.S.E. (1996), SUSE 5.1 (1998), Red Hat 6.0 (1999), Mandrake 8.0 (2001), and Fedora 1 (2003).

Clamping Down On VPNs
by Lawrence D'Oliveiro 12 Aug '17

12 Aug '17

“The Listening Post” on Al Jazeera this week <http://www.aljazeera.com/programmes/listeningpost/2017/08/great-firewall-up…> talks among other things about the attempts by China and other countries to clamp down on their citizens’ access to virtual private networks. While these have many legitimate “non-political” applications (particularly for business), they can also be used to bypass state censorship. China, as you may know, has the most advanced system for restricting access within its borders to sources of content outside them that the state has deemed undesirable. The plan for ensuring that this clampdown on VPNs is done in a way that doesn’t hurt its own business interests is to license VPN providers within the country, and make sure they allow state monitoring, and do not give access to “undesirable” sites. Apple, for one, has acquiesced to China’s demands and removed VPN apps from its Iphone app store within the PRC. However, as one of those interviewed in the piece points out, on the Android side there are 400 different app stores accessible within China, and it would be quite another matter to make sure they all comply with the new law.

exa a modern replacement for ls written in rust for Linux/Unix
by Peter Reutemann 09 Aug '17

'ls is a command to show files in Linux and Unix-like operating systems. A ls command first appeared in a version of AT&T UNIX as well as in Multics. BSD and GNU Coreutils package provides the ls command with minor syntax changes. There is now third alternative named exa. It is a modern replacement for ls. The exa uses colors for information by default, helping you distinguish between many types of files, such as whether you are the owner, or in the owning group. It also has extra features not present in the original ls, such as viewing the Git status for a directory or recursing into directories with a tree view.

Firefox 55 Arrives With WebVR on Windows, Performance Panel, and Click-to-Play Flash
by Peter Reutemann 08 Aug '17

08 Aug '17

'Mozilla today made available a new update to Firefox for Windows to introduce support for WebVR, that the company says, will enable desktop VR users to dive into web-based experiences with ease. Firefox 55 also includes performance panel, faster startup when restoring multiple tabs, a quicker way to search across various search engines, and click-to-play Flash by default. From a report: WebVR is an experimental JavaScript API that provides support for virtual reality devices, such as the HTC Vive, Oculus Rift, and Google Cardboard. As its name implies, the technology is meant for browsers. If you find a web game or app that supports VR, just click the VR goggles icon visible on the web page to experience it using your VR headset. WebVR supports navigating and controlling VR experiences with handset controllers or your movements in physical space. [...] Firefox 55 also allows users to adjust the number of processes and how much resources they want to allocate to any of them. This setting is at the bottom of the General section in Options. In fact, if your computer has more than 8GB of RAM, Mozilla recommends "bumping up the number of content processes that Firefox uses" because it will make Firefox faster, though at the expense of using more memory. In its own tests on Windows 10, the company found that Firefox uses less memory than Chrome, even with eight content processes running.' -- source: https://tech.slashdot.org/story/17/08/08/143246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla’s new file-transfer service isn’t perfect, but it’s drop-dead easy

'Mozilla is testing a new service that makes it dead simple and quick for people to semi-securely share files with anyone on the Internet. Send, as the service is called, allows senders to encrypt any 1-gigabyte or less file and upload it to a Mozilla server.

Mozilla will automatically delete the encrypted file as soon as it's downloaded or within 24 hours of being uploaded, even if no one has downloaded it.' -- source: https://arstechnica.com/information-technology/2017/08/mozillas-new-file-tr… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

OpenSSL Support In Debian Unstable Drops TLS 1.0/1.1 Support
by Peter Reutemann 07 Aug '17

07 Aug '17

'Debian Linux "sid" is deprecating TLS 1.0 Encryption. A new version of OpenSSL has been uploaded to Debian Linux unstable. This version disables the TLS 1.0 and 1.1 protocol. This currently leaves TLS 1.2 as the only supported SSL/TLS protocol version. This will likely break certain things that for whatever reason still don't support TLS 1.2. I strongly suggest that if it's not supported that you add support for it, or get the other side to add support for it. OpenSSL made a release 5 years ago that supported TLS 1.2. The current support of the server side seems to be around 90%. I hope that by the time Buster releases the support for TLS 1.2 will be high enough that I don't need to enable them again. This move caused some concern among Debian users and sysadmins. If you are running Debian Unstable on server tons of stuff is going to broken cryptographically. Not to mention legacy hardware and firmware that still uses TLS 1.0. On the client side (i.e. your users), you need to use the latest version of a browser such as Chrome/Chromium and Firefox. The Older version of Android (e.g. Android v5.x and earlier) do not support TLS 1.2. You need to use minimum iOS 5 for TLS 1.2 support. Same goes with SMTP/mail servers, desktop email clients, FTP clients and more. All of them using old outdated crypto. This move will also affect for Android 4.3 users or stock MS-Windows 7/IE users (which has TLS 1.2 switched off in Internet Options.) Not to mention all the mail servers out there running outdated crypto.' -- source: https://linux.slashdot.org/story/17/08/07/1823244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GNOME's Text Editor gedit 'No Longer Maintained', Needs New Developers
by Peter Reutemann 06 Aug '17

06 Aug '17

'AmiMoJo brings news about gedit, the default text editor for GNOME: In a post to the gedit mailing list, Sébastien Wilmet states that gedit is no longer maintained and asks "any developer interested to take over the maintenance of gedit?" Just in case you were considering it, he warns "BTW while the gedit core is written in C (with a bit of Objective-C for Mac OS X support), some plugins are written in Vala or Python. If you take over gedit maintenance, you'll need to deal with four programming languages (without counting the build system). The Python code is not compiled, so when doing refactorings in gedit core, good luck to port all the plugins (the Python code is also less "greppable" than C). At least with Vala there is a compiler, even if I would not recommend Vala." Sébastien's comments were surrounded by a <rant-on-languages> tag, but they're still crying out for some serious discussion. Any Slashdot readers want to share their own insights on Python, some fond thoughts on gedit, or suggestions for maintaining a great piece of open source software?' -- source: https://tech.slashdot.org/story/17/08/05/025227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Red Hat Acquires Data-Cleaning Company Permabit
by Peter Reutemann 06 Aug '17

'Business software company Red Hat said on Monday that it is acquiring the technology assets of Permabit, a small company that specializes in cleaning up corporate data to make storage more efficient and data access faster. Terms of the deal were not disclosed but a Red Hat spokesman said 16 people from Permabit will be joining that company... While the conventional wisdom is that data storage is cheap, it is not free. And with companies turning to more expensive flash storage, it saves money to remove redundant data, said Richard Fichera, vice president and principal analyst at Forrester Research... Red Hat, which sells a version of the Linux operating system used by many Fortune 500 companies, also offers its own storage software. And, it wants to become a more formidable challenger in data storage, a goal that can be furthered by buying Permabit's technology, Fichera said. Slashdot reader See Attached points out that this week Red Hat also released RHEL 7.4, which introduces support for Network Bound Disk Encryption (NBDE) and system protection against intrusive USB devices.' -- source: https://linux.slashdot.org/story/17/08/05/0453223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Kernel Hardeners Grsecurity Sue Open Source's Bruce Perens
by Peter Reutemann 06 Aug '17

06 Aug '17

'In late June, noted open-source programmer Bruce Perens [a longtime Slashdot reader] warned that using Grsecurity's Linux kernel security could invite legal trouble. "As a customer, it's my opinion that you would be subject to both contributory infringement and breach of contract by employing this product in conjunction with the Linux kernel under the no-redistribution policy currently employed by Grsecurity," Perens wrote on his blog. The following month, Perens was invited to court. Grsecurity sued the open-source doyen, his web host, and as-yet-unidentified defendants who may have helped him draft that post, for defamation and business interference. Grsecurity offers Linux kernel security patches on a paid-for subscription basis. The software hardens kernel defenses through checks for common errors like memory overflows. Perens, meanwhile, is known for using the Debian Free Software Guidelines to draft the Open Source Definition, with the help of others. Grsecurity used to allow others to redistribute its patches, but the biz ended that practice for stable releases two years ago and for test patches in April this year. It offers its GPLv2 licensed software through a subscription agreement. The agreement says that customers who redistribute the code -- a right under the GPLv2 license -- will no longer be customers and will lose the right to distribute subsequent versions of the software. According to Perens, "GPL version 2 section 6 explicitly prohibits the addition of terms such as this redistribution prohibition." A legal complaint (PDF) filed on behalf of Grsecurity in San Francisco, California, insists the company's software complies with the GPLv2. Grsecurity's agreement, the lawsuit states, only applies to future patches, which have yet to be developed. Perens isn't arguing that the GPLv2 applies to unreleased software. Rather, he asserts the GPLv2, under section 6, specifically forbids the addition of contractual terms.' -- source: https://yro.slashdot.org/story/17/08/04/2233239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Browser Extensions Are Undermining Privacy
by Peter Reutemann 06 Aug '17

06 Aug '17

'pizzutz writes: Chrome's popular Web Developer plugin was briefly hijacked on Wednesday when an attacker gained control of the author's Google account and released a new version (0.49) which injected ads into web pages of more than a million users who downloaded the update. The version was quickly replaced with an uncompromised version (0.5) and all users are urged to update immediately. Lauren Weinstein has a broader warning: While the browser firms work extensively to build top-notch security and privacy controls into the browsers themselves, the unfortunate fact is that these can be undermined by add-ons, some of which are downright crooked, many more of which are sloppily written and poorly maintained. Ironically, some of these add-on extensions and apps claim to be providing more security, while actually undermining the intrinsic security of the browsers themselves. Others (and this is an extremely common scenario) claim to be providing additional search or shopping functionalities, while actually only existing to silently collect and sell user browsing activity data of all sorts. Lauren also warns about sites that "push users very hard to install these privacy-invasive, data sucking extensions" -- and believes requests for permissions aren't a sufficient safeguard for most users. "Expecting them to really understand what these permissions mean is ludicrous. We're the software engineers and computer scientists -- most users aren't either of these. They have busy lives -- they expect our stuff to just work, and not to screw them over."' -- source: https://yro.slashdot.org/story/17/08/05/2122210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The Windows console is getting a new, easier to read color scheme
by Lawrence D'Oliveiro 03 Aug '17

03 Aug '17

“Even with this work, the Windows console is still weak compared to its counterparts in macOS and Linux. In Windows, the operating systems-supplied console windows are closely tied to the command-line applications that use them; it's impossible to create a command-line application that isn't attached to a Windows console window. Linux and macOS offer a separation between the software that's displaying the console apps and the console apps themselves. Those operating systems have a built-in default console, but unlike Windows, they don't have to use it; third-party software can fill the same role. “Attractive, modern terminal applications like iTerm on macOS and Unix stalwarts such as screen (which enables multiple command-line shells to share a single console window) take advantage of this extensibility. Neither kind of application can be readily developed for command-line apps on Windows, and while people have tried to work around Windows' limitations (for example, by hiding the Windows built-in console windows off-screen somewhere), the results are imperfect. We're told that there are plans in store to finally address this weakness of Windows, though what the solution will be is at present unknown.” <https://arstechnica.com/gadgets/2017/08/the-windows-console-is-getting-a-ne…>

Trust Me, I’m A Random-Number Generator
by Lawrence D'Oliveiro 30 Jul '17

30 Jul '17

SK Telecom has created a “quantum random number generator” chip <https://www.theregister.co.uk/2017/07/26/sk_telecom_makes_light_of_random_n…>. Seems like slapping the label “quantum” on anything is enough to make people believe you know what you are talking about. Random-number generators are notorious for being easily subverted. And hearing things like “SK Telecom hasn't specified what kind [of quantum noise source they are using]” is not exactly reassuring. You can never be sure your random numbers are truly random. But you try to stack the deck as much in your favour as you can. The Linux kernel mixes in several sources of entropy to feed /dev/random (and from there, /dev/urandom), in the hope that, as long as one of them remains unsubverted (intentionally or otherwise), the output can be trusted. This is also the principle behind the Fortuna PRNG <https://en.wikipedia.org/wiki/Fortuna_(PRNG)>, which well-known computer security guru Bruce Schneier had a hand in.

Some Low-Cost Android Phones Come at a Price -- Your Privacy

'At $60, the BLU R1 HD is the top-selling phone on Amazon. Last November, researchers caught it secretly sending private data to China. Shanghai Adups Technology, the group behind the spying software on the BLU R1 HD, called it a mistake. But analysts at Kryptowire found the software provider is still making the same "mistake" on other phones. At the Black Hat security conference in Las Vegas on Wednesday, researchers from Kryptowire, a security firm, revealed that Adups' software is still sending a device's data to the company's server in Shanghai without alerting people. But now, it's being more secretive about it. "They replaced them with nicer versions," Ryan Johnson, a research engineer and co-founder at Kryptowire, said. "I have captured the network traffic of them using the Command and Control channel when they did it." An Adups spokeswoman said that it had resolved the issues in 2016 and that the issues "are not existing anymore." Kryptowire said it has observed the company sending data without telling users on at least three different phones.' -- source: https://it.slashdot.org/story/17/07/26/187258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Wellcome Trust Wants To Share
by Lawrence D'Oliveiro 26 Jul '17

26 Jul '17

You’ve probably heard of the Wellcome Trust: they’re a UK-based nonprofit that funds scientific research, primarily into health. They’ve long had an open-access policy, meaning that “all original research articles and scholarly monographs resulting from our funding are made freely available”. Contrast this with what more commonly happens with scientific research, where the journal publishers get exclusive copyright over the papers, and charge an arm and a leg to everyone wanting a copy. Now the Wellcome Trust is going even further, and requiring open access in a timely manner to the raw research data (within reasonable limits, such as privacy concerns etc), material such as cell lines, antibodies and reagents, and also any software developed. No actual mention of “open source” or “Free software” licences as such, though; the news article only uses the word “freeware”, which I’m not sure is the word they should be using. <https://www.theregister.co.uk/2017/07/25/wellcome_trust_extends_research_da…> <https://wellcome.ac.uk/news/our-new-policy-sharing-research-data-what-it-me…>

'Devil's Ivy' Is Another Wake-Up Call for IoT Security
by Peter Reutemann 26 Jul '17

26 Jul '17

'The vulnerability -- called Devil's Ivy or CVE-2017-9765 -- was made public last week by Senrio, a company that specializes in IoT security. It initially found the bug in the M3004 model security camera marketed by Axis Communications, but further research found that 249 of Axis's 251 surveillance camera models are affected. Although that's of lot of devices, it's only the tip of the iceberg, as the problem isn't with code that's native to Axis products but is in gSOAP, an open source web services library that's used by many developers.

Using Gnome Disk Utility - "Disks" - to install distro iso to USB stick.
by Ian Stewart 24 Jul '17

24 Jul '17

Hi, I mentioned this at last nights meeting, so here is the link info. You might be used to burning distro iso image files to USB sticks using the dd command line utility, or Ubuntu's Startup Disk Creator gui application. The Fedora 21 Installation Guide<https://docs.fedoraproject.org/en-US/Fedora/21/html/Installation_Guide/inde…> describes another way<https://docs.fedoraproject.org/en-US/Fedora/21/html/Installation_Guide/sect…>. You launch the Gnome Disk Utility by clicking on the Disks application icon, or from the command line as gnome-disks, and follow these instructions... Procedure 3.4. Creating USB media with GNOME Disks 1. On a system with GNOME, or with the gnome-disk-utility package installed, open Disks using the system menu. 2. Click your USB device in the left column. 3. Click the menu icon in the upper right corner of the window, and choose the Restore Disk Image option. 4. Navigate to your image file and click Start Restoring. After a few minutes, it will report the process is complete and your installation media will be ready to use. cheers, Ian.

How a VC-Funded Company Is Undermining the Open-Source Community
by Peter Reutemann 24 Jul '17

24 Jul '17

'Is a $4 million venture capital-funded startup stealthily taking over popular coding tools and injecting ads and spyware into them? That's what some programmers fear may be happening. It is one of the most troubling scandals to hit the open-source community -- a robust network of programmers who work on shared tools for free -- in recent memory. It started back in April, when a programmer noticed a strange change to an open-source tool called Minimap. Minimap has had more than 3.5 million downloads, but like many open-source tools, it was maintained by a single person who no one knew much about other than their username: @abe33. At some point, @abe33, whose real name is Cedric Nehemie, was hired by Kite. Kite was started by Adam Smith, a successful tech entrepreneur who raised funding from a slew of big names including the CEO of Dropbox and the creator of WordPress. It is unclear what Kite's business model is, but it says it uses machine-learning techniques to make coding tools. Its tools are not open source. After being hired by Kite, @abe33 made an update to Minimap. The update was titled "Implement Kite promotion," and it appeared to look at a user's code and insert links to related pages on Kite's website. Kite called this a useful feature. Programmers said it was not useful and was therefore just an ad for an unrelated service, something many programmers would consider a violation of the open-source spirit. "It's not a feature, it's advertising -- and people don't want it, you want it," wrote user @p-e-w. "The least you can do is own up to that." "I have to wonder if your goal was to upset enough people that you'd generate real attention on various news sites and get Kite a ton of free publicity before your next funding round," @DevOpsJohn wrote. "That's the only sane explanation I can find for suddenly dropping ads into the core of one of the oldest and most useful Atom plugins." [...] Although Kite has no business model yet, it's widely thought in Silicon Valley that having users is the first step toward profitability. Adding users potentially benefits the company in another way, by giving it access to precious data. Kite says it uses machine learning tactics to make the best coding helper tools possible. In order to do that, it needs tons of data to learn from. The more code it can look at, the better its autocomplete suggestions will get, for example.' -- source: https://developers.slashdot.org/story/17/07/24/0118202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

DNS Lib Underscore Bug Bites Everyone's Favorite Init Tool, Blanks Netflix
by Peter Reutemann 24 Jul '17

24 Jul '17

'Systemd doing what it does best. From a report on The Register: A few Penguinistas spent a weekend working out why they can't get through to Netflix from their Linux machines, because when they tried, their DNS lookups failed. The issue emerged over the weekend, when Gentoo user Dennis Schridde submitted a bug report to the Systemd project. Essentially, he described a failure within systemd-resolve, a Systemd component that turns human-readable domain names into IP addresses for software, like web browsers, to connect to. The Systemd resolver couldn't look up Netflix's servers for Schridde's web browser, according to the report. In his detailed post, Schridde said he expected this to happen: ipv6_1-cxl0-c088.1.lhr004.ix.nflxvideo.net gets resolved to 37.77.187.142 or 2a00:86c0:5:5::142. When in reality, that wasn't happening, so Netflix couldn't be reached on his box. His speculation that libidn2, which adds internationalised domain names support to the resolver, was at fault turned out to be accurate. Rebuilding Systemd without that library cleared the problem.' -- source: https://linux.slashdot.org/story/17/07/24/1558259 Please, no flame war...

Mysterious Mac Malware Has Infected Hundreds of Victims For Years
by Peter Reutemann 24 Jul '17

24 Jul '17

'A mysterious piece of malware has been infecting hundreds of Mac computers for years -- and no one noticed until a few months ago. The malware is called "FruitFly," and one of its variants, "FruitFly 2" has infected at least 400 victims over the years. FruitFly 2 is intriguing and mysterious: its goals, who's behind it, and how it infects victims, are all unknown. Earlier this year, an ex-NSA hacker started looking into a piece of malware he described to me as "unique" and "intriguing." It was a slightly different strain of a malware discovered on four computers earlier this year by security firm Malwarebytes, known as "FruitFly." This first strain had researchers scratching their heads. On the surface, the malware seemed "simplistic." It was programmed mainly to surreptitiously monitor victims through their webcams, capture their screens, and log keystrokes. But, strangely, it went undetected since at least 2015. There was no indication of who could be behind it, and it contained "ancient" functions and "rudimentary" remote control capabilities, Malwarebytes's Thomas Reed wrote at the time.' -- source: https://it.slashdot.org/story/17/07/24/1719255 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla's New Open Source Voice-Recognition Project Wants Your Voice
by Peter Reutemann 23 Jul '17

23 Jul '17

'Mozilla is building a massive repository of voice recordings for the voice apps of the future -- and it wants you to add yours to the collection. The organization behind the Firefox browser is launching Common Voice, a project to crowdsource audio samples from the public. The goal is to collect about 10,000 hours of audio in various accents and make it publicly available for everyone... Mozilla hopes to hand over the public dataset to independent developers so they can harness the crowdsourced audio to build the next generation of voice-powered apps and speech-to-text programs... You can also help train the speech-to-text capabilities by validating the recordings already submitted to the project. Just listen to a short clip, and report back if text on the screen matches what you heard... Mozilla says it aims is to expand the tech beyond just a standard voice recognition experience, including multiple accents, demographics and eventually languages for more accessible programs. Past open source voice-recognition projects have included Sphinx 4 and VoxForge, but unfortunately most of today's systems are still "locked up behind proprietary code at various companies, such as Amazon, Apple, and Microsoft."' -- source: https://news.slashdot.org/story/17/07/22/2026208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bruce Schneier’s Book Review: “Twitter And Tear Gas”

There are two opposing models of how the Internet has changed protest movements. The first is that the Internet has made protesters mightier than ever. ... The second is that it has made them more ineffectual. Derided as "slacktivism" or "clicktivism," the ease of action without commitment can result in movements like Occupy petering out in the US without any obvious effects. Of course, the reality is more nuanced ... <https://www.schneier.com/blog/archives/2017/07/book_review_twi.html>

Fedora 26 Linux Distro Released

Also new is LibreOffice 5.3, which is an indispensable suite for productivity. If you still use mp3 music files I've moved onto streaming), support should be baked in for both encoding and decoding. "The latest version of Fedora's desktop-focused edition provides new tools and features for general users as well as developers. GNOME 3.24 is offered with Fedora 26 Workstation, which includes a host of updated functionality including Night Light, an application that subtly changes screen color based on time of day to reduce effect on sleep patterns, and LibreOffice 5.3, the latest update to the popular open source office productivity suite. For developers, GNOME 3.24 provides matured versions of Builder and Flatpak to make application development for a variety of systems, including Rust and Meson, easier across the board," says the Fedora Project.' -- source: https://linux.slashdot.org/story/17/07/11/1722202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Multics Lives!

I previously mentioned <https://list.waikato.ac.nz/pipermail/wlug/2015-August/013714.html> the old Multics OS, which was so complex and so delayed in its development that a group of folks at AT&T Bell Labs decided not to wait and created their own, less ambitious OS instead, deciding to call it “UNIX” as a sort of pun on “Multics”. Well, at long last <https://www.theregister.co.uk/2017/07/10/multics_resurrected_in_new_simulat…>, you can now run Multics for yourself. The original mainframe hardware is long gone, but today’s PCs can easily support a suitable software emulation without breaking too much of a sweat--even a Raspberry π 2, it seems, can run the emulation at something close to the speed of the early mainframe units. All it took was some suitably dedicated people to build such an emulator. And now you can download their work and try it out for yourself.

Let’s Encrypt: Wildcard Certs Coming Soon
by Lawrence D'Oliveiro 07 Jul '17

Anybody using Let’s Encrypt? Having recently set it up for a client, I’m really impressed with it. It gives you HTTPS certs for your web servers at no cost, and with very little effort, since the entire process is automated (with authentication via the “ACME” protocol). The certs are only valid for 90 days, to try to minimize potential damage from any compromises, but the renewal process is equally easy to automate. The one service they haven’t offered up to now is certs for wildcard domains (e.g. “*.example.com”). Looks like they will soon have a procedure for this, too <https://arstechnica.com/information-technology/2017/07/lets-encrypt-to-star…>.

OneDrive Has Stopped Working On Non-NTFS Drives
by Peter Reutemann 07 Jul '17

07 Jul '17

'OneDrive users around the world have been upset to discover that with its latest update, Microsoft's cloud file syncing and storage system no longer works with anything other than disks formatted with the NTFS file system. Both older file systems, such as FAT32 and exFAT, and newer ones, such as ReFS, will now provoke an error message when OneDrive starts up. To continue to use the software, files will have to be stored on an NTFS volume. While FAT disks can be converted, ReFS volumes must be reformatted and wiped. This has left various OneDrive users unhappy. While NTFS is the default file system in Windows, people using SD cards to extend the storage on small laptops and tablets will typically use exFAT. Similarly, people using Storage Spaces to manage large, redundant storage volumes will often use ReFS. The new policy doesn't change anything for most Windows users, but those at the margins will feel hard done by. Microsoft said in a statement that it "discovered a warning message that should have existed was missing when a user attempted to store their OneDrive folder on a non-NTFS filesystem -- which was immediately remedied." According to Ars, Microsoft's position, apparently, is that OneDrive should always have warned about these usage scenarios and that it's only a bug or an oversight that allowed non-NTFS volumes to work.' -- source: https://hardware.slashdot.org/story/17/07/06/2012255 Time to switch to ownCloud! :-) https://owncloud.org/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

iPhone Bugs Are Too Valuable To Report To Apple
by Peter Reutemann 07 Jul '17

07 Jul '17

'Last year, Apple launched a long-awaited bug bounty program to reward friendly hackers who report flaws in the iPhone to the company. Despite inviting some of the best hackers in the world to join, it's a bit of a flop so far. The iPhone's security is so tight that it's hard to find any flaws at all, which leads to sky-high prices for bugs on the grey market. Researchers I spoke to are reluctant to report bugs both because they are so valuable and because reporting some bugs may actually prevent them from doing more research. "People can get more cash if they sell their bugs to others," said Nikias Bassen, a security researcher for the company Zimperium, and who joined Apple's program last year. "If you're just doing it for the money, you're not going to give [bugs] to Apple directly." Patrick Wardle, a former NSA hacker who now specializes in MacOS research and was invited to the Apple bug bounty program, agreed. He said that iOS bugs are "too valuable to report to Apple."' -- source: https://apple.slashdot.org/story/17/07/06/1551210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Severe' Systemd Bug Allowed Remote Code Execution For Two Years
by Peter Reutemann 06 Jul '17

06 Jul '17

'A flaw in systemd, the init system used on many Linux systems, can be exploited using a malicious DNS query to either crash a system or to run code remotely. The vulnerability resides in the daemon systemd-resolved and can be triggered using a TCP payload, according to Ubuntu developer Chris Coulson. This component can be tricked into allocating less memory than needed for a look-up. When the reply is bigger it overflows the buffer allowing an attacker to overwrite memory. This would result in the process either crashing or it could allow for code execution remotely. "A malicious DNS server can exploit this by responding with a specially crafted TCP payload to trick systemd-resolved in to allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it," is how Coulson put it. Affected Linux vendors have pushed out patches -- but the bug has apparently been present in systemd code since June of 2015. And long-time Slashdot reader walterbyrd also reports a recently-discovered bug where systemd unit files that contain illegal usernames get defaulted to root.' -- source: https://it.slashdot.org/story/17/07/03/0343258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GnuPG crypto library cracked, look for patches
by Lawrence D'Oliveiro 05 Jul '17

05 Jul '17

What they found is that the libgcrypt library used what's called “sliding windows”, a method for carrying out the mathematics of cryptography – but one that's known to leak data. ... What they found was an unpleasant surprise: a complete break of the library's RSA-1024... <https://www.theregister.co.uk/2017/07/04/gnupg_crypto_library_cracked_look_…> Cue the conspiracy theorists lining up to say “Given the controversy surrounding GnuPG and the way they operate, one just has to wonder "bug or backdoor?"”

Latte Dock – An Elegant and Intuitive Dock for Your Tasks and Plasmoids
by Peter Reutemann 03 Jul '17

'Latte Dock is arguably the best dock app for KDE Plasma especially since the release of its stable version 0.6 in April. It is based on plasma frameworks, that working together to provide users with an elegant and intuitive experience while going about their everyday PC tasks. Latte Dock is unlike some dock apps in the market in the sense that it lets you replace your desktop panels completely. You can use it to run multiple docks on one screen, mimic several panel layouts including that of Unity and Plasma, set animation styles especially using its parabolic zoom effects, and organize Plasmoids.' -- source: https://www.fossmint.com/latte-dock-an-elegant-and-intuitive-dock-for-kde-p… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Kernel 4.12 Officially Released
by Peter Reutemann 03 Jul '17

03 Jul '17

'After seven weeks of announcing release candidate versions, Linus Torvalds today informs the Linux community through a mailing list announcement about the general availability of the Linux 4.12 kernel series. Development on the Linux 4.12 kernel kicked off in mid-May with the first release candidate, and now, seven weeks later we can finally get our hands on the final release... A lot of great improvements, new hardware support, and new security features were added during all this time, which makes it one of the biggest releases, after Linux 4.9... Prominent features of the Linux 4.12 kernel include initial support for AMD Radeon RX Vega graphics cards, intial Nvidia GeForce GTX 1000 "Pascal" accelerated support, implementation of Budget Fair Queueing (BFQ) and storage-I/O schedulers, more MD RAID enhancements, support for Raspberry Pi's Broadcom BCM2835 thermal driver, a lot of F2FS optimizations, as well as ioctl for the GETFSMAP space mapping ioctl for both XFS and EXT4 filesystems. Linus said in announcing the release that "I think only 4.9 ends up having had more commits," also noting that 4.9 was a Long Term Support kernel, whereas "4.12 is just plain big." "There's also nothing particularly odd going on in the tree - it's all just normal development, just more of it than usual."' -- source: https://linux.slashdot.org/story/17/07/03/0410253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

HTTPS Certificate Revocation Doesn’t Work: Some Fixes
by Lawrence D'Oliveiro 03 Jul '17

03 Jul '17

The traditional mechanisms for revoking compromised TLS/SSL certifications--cert revocation lists (CRLs) and Online Certificate Status Protocol (OCSP)--don’t really work. But something can be done about this, in the form of “OCSP Must Staple”. Also the issue of rogue certifications--certs issued for your domain without your knowledge or permission--can be mitigated with Certificate Transparency (CT), where the issuing Certificate Authorities (CAs) publish all the certs they have given out, to allow crosschecks. There is also Certificate Authority Authorization (CAA), where the DNS entry for your domain specifies which CA(s) are allowed to issue certs for it. <https://arstechnica.com/security/2017/07/https-certificate-revocation-is-br…>

Debian Linux reveals Intel Skylake and Kaby Lake processors have broken hyper-threading
by Peter Reutemann 03 Jul '17

03 Jul '17

'Do you have an Intel Skylake and Kaby Lake processor under your computer's hood? Have you experienced unexplained application and system hiccups, data corruption, or data loss? It could be because your chipset has hyper-threading enabled and the chips are malfunctioning. Henrique de Moraes Holschuh, a Debian Linux developer, revealed the Intel chip problem on the Debian developer list. Officially, Intel hasn't acknowledged the problem, but engineers at Dell and Intel have told me that the problem, and its fix, exists. This processor/microcode defect has been found on Intel Skylake and Intel Kaby Lake processors with hyper-threading enabled. Besides these 6th and 7th generation Intel Core processors, its also found on its related server processors, such as Xeon v5 and Xeon v6, and some select Intel Pentium processor models. While the Debian community revealed the problem, it's not Linux-specific. Any operating system -- Windows, macOS,FreeBSD, you name it -- can run into the problem. According to Intel chip errata, "Under complex micro-architectural conditions, short loops of less than 64 instructions that use AH, BH, CH or DH registers as well as their corresponding wider register (e.g. RAX, EAX or AX for AH) may cause unpredictable system behavior. This can only happen when both logical processors on the same physical processor are active." This will lead to the computer experiencing "unpredictable system behavior." What programs will cause a computer to act up? That's a good question, and we don't have a good answer. As Holschuh wrote, "We do not have enough information at this time to know how much software out there will trigger this specific defect."' -- source: http://www.zdnet.com/article/debian-linux-reveals-intel-skylake-kaby-lake-p… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

23 Years Of The Open Source 'FreeDOS' Project
by Peter Reutemann 03 Jul '17

03 Jul '17

Not quite Linux, but a good example of an open-source project: 'Jim Hall is celebrating the 23rd birthday of the FreeDOS Project, calling it "a major milestone for any free software or open-source software project," and remembering how it all started. An anonymous reader quotes Linux Journal: If you remember Windows 3.1 at the time, it was a pretty rough environment. I didn't like that you could interact with Windows only via a mouse; there was no command line. I preferred working at the command line. So I was understandably distressed in 1994 when I read via various tech magazines that Microsoft planned to eliminate MS-DOS with the next version of Windows. I decided that if the next evolution of Windows was going to be anything like Windows 3.1, I wanted nothing to do with it... I decided to create my own version of DOS. And on June 29, 1994, I posted an announcement to a discussion group... Our "PD-DOS" project (for "Public Domain DOS") quickly grew into FreeDOS. And 23 years later, FreeDOS is still going strong! Today, many people around the world install FreeDOS to play classic DOS games, run legacy business software or develop embedded systems... FreeDOS has become a modern DOS, due to the large number of developers that continue to work on it. You can download the FreeDOS 1.2 distribution and immediately start coding in C, Assembly, Pascal, BASIC or a number of other software development languages. The standard FreeDOS editor is quite nice, or you can select from more than 15 different editors, all included in the distribution. You can browse websites with the Dillo graphical web browser, or do it "old school" via the Lynx text-mode web browser. And for those who just want to play some great DOS games, you can try adventure games like Nethack or Beyond the Titanic, arcade games like Wing and Paku Paku, flight simulators, card games and a bunch of other genres of DOS games. On his "Open Source Software and Usability" blog, Jim says he's been involved with open source software "since before anyone coined the term 'open source'," and first installed Linux on his home PC in 1993. Over on the project's blog, he's also sharing appreciative stories from FreeDOS users and from people involved with maintaining it (including memories of early 1980s computers like the Sinclair ZX80, the Atari 800XL and the Coleco Adam). Any Slashdot readers have their own fond memories to share?' -- source: https://news.slashdot.org/story/17/07/02/1710200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Ubuntu Disputes 'Ads In MOTD' Claims

'Thursday Lproven (Slashdot reader #6030) wrote: It appears that Ubuntu is using a feature it has added -- intended to insert headlines of breaking tech news (security alerts and so on) into the Message of the Day displayed at login to the console -- to display advertising and promotional messages.

'This week the Free Software Foundation awarded its coveted 'Respects Your Freedom' certification to 15 products -- more than doubling the number of certified products (from 12 to 27) since the program began in 2012. An anonymous reader writes: The non-profit FSF certified six different laptops, two docking stations, three WiFi USB adapters and two internal WiFi devices, a mainboard, and their first-ever certified Bluetooth device, the TET-BT4 USB adapter. The products are all from Technoethical (formerly Tehnoetic), a Romania-based company who previously had just one mini wireless USB adapter on their list of FSF-certified products. "In 2014 we started selling hardware compatible with fully free systems in order to fund the free software activism work that we've been doing with our foundation," said Technoethical founder, Tiberiu C. Turbureanu. "Since then, we worked hard to build a hardware catalog that allows free software users to choose what best fits their computing needs, while also helping with the funding of different free software projects."

Why do printers add secret tracking dots?
by Ian Stewart 17 Jun '17

17 Jun '17

Hi, This is new news to me, however it looks like its been known about for years. cheers, Ian. According to this<http://www.bbc.com/future/story/20170607-why-printers-add-secret-tracking-d…> BBC technology article, colour laser printers add yellow dots to each page printed that identify the date and time it was printed and the printers serial number. "At that point, experts began taking a closer look at the document, now publicly available on the web. They discovered something else of interest: yellow dots in a roughly rectangular pattern repeated throughout the page. They were barely visible to the naked eye, but formed a coded design. After some quick analysis, they seemed to reveal the exact date and time that the pages in question were printed: 06:20 on 9 May, 2017 – at least, this is likely to be the time on the printer’s internal clock at that moment. The dots also encode a serial number for the printer." The Electronic Frontier Foundation (EFF) maintained a List of Printers Which Do or Do Not Display Tracking Dots<https://www.eff.org/pages/list-printers-which-do-or-do-not-display-tracking…> ...but "This list is no longer being updated." "(Added 2015) Some of the documents that we previously received through FOIA suggested that all major manufacturers of color laser printers entered a secret agreement with governments to ensure that the output of those printers is forensically traceable. Although we still don't know if this is correct, or how subsequent generations of forensic tracking technologies might work, it is probably safest to assume that all modern color laser printers do include some form of tracking information that associates documents with the printer's serial number. (If any manufacturer wishes to go on record with a statement to the contrary, we'll be happy to publish that here.) (Added 2017) REMINDER: IT APPEARS LIKELY THAT ALL RECENT COMMERCIAL COLOR LASER PRINTERS PRINT SOME KIND OF FORENSIC TRACKING CODES, NOT NECESSARILY USING YELLOW DOTS. THIS IS TRUE WHETHER OR NOT THOSE CODES ARE VISIBLE TO THE EYE AND WHETHER OR NOT THE PRINTER MODELS ARE LISTED HERE. THIS ALSO INCLUDES THE PRINTERS THAT ARE LISTED HERE AS NOT PRODUCING YELLOW DOTS."

Programmers Who Indent With Spaces Earn More Than Those Using Tabs
by Lawrence D'Oliveiro 16 Jun '17

16 Jun '17

According to this report <https://arstechnica.com/information-technology/2017/06/according-to-statist…>, the latest Stack Overflow developer survey shows a wide gap between the earnings of those who use spaces to indent their code, versus those who use tabs. Speaking as someone who moved from tabs to spaces about a decade ago, I don’t understand why the author seems so cut up about this. It makes about as much sense as vi/vim users complaining about Emacs users. (The guy also seems to put Perl and PHP on the same intellectual level, which I think tells you all you need to know about the state of his mental health...) And he forgot to link to the actual survey results, which are here <https://insights.stackoverflow.com/survey/2017>. I can’t see where he got the information about the correlation between tabs/spaces and income--all I can see is that among professional developers, spaces are more popular, whereas among all developers, tabs are more popular.

Malware Uses Obscure Intel CPU Feature To Steal Data and Avoid Firewalls
by Peter Reutemann 09 Jun '17

09 Jun '17

'Microsoft's security team has come across a malware family that uses Intel's Active Management Technology (AMT) Serial-over-LAN (SOL) interface as a file transfer tool. The problem with Intel AMT SOL is that it's part of Intel's ME, a separate chip inside Intel CPUs that runs its own OS and stays on even when the main CPU is off. Inside Intel's ME, AMT SOL opens a virtual network interface which works even when the PC is turned off. Furthermore, because this virtual network interface runs inside ME, firewalls and security products installed on the main OS won't detected malware using AMT SOL to exfiltrate data. The malware was created and used by a nation-state cyber-espionage unit codenamed PLATINUM, active since 2009, and which has targeted countries around the South China Sea. PLATINUM is by far one of the most sophisticated hacking groups ever discovered. Last year [PDF], the OS maker said the group was installing malware by abusing hotpatching — a mechanism that allows Microsoft to issue updates that tap into active processes and upgrade applications or the operating system without having to reboot the computer. Details about PLATINUM's recent targets and attacks are available in a report [PDF] Microsoft released yesterday.' -- source: https://it.slashdot.org/story/17/06/08/1754244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Is Intel Threatening To Sue Microsoft Over x86-on-ARM?
by Lawrence D'Oliveiro 09 Jun '17

09 Jun '17

Intel has put out a press release warning anybody working on x86-emulation technology to beware of infringing its patents <https://arstechnica.com/information-technology/2017/06/intel-fires-warning-…>. The article suggests that the timing of this announcement is a warning specifically to Microsoft, and possibly also Qualcomm, over their upcoming release of Windows-10-on-ARM machines. Even if this is so, I’m not sure I agree that “This compatibility makes these ARM-based machines a threat to Intel in a way that Windows RT never was”. The simple fact is that the performance of emulated x86 code on ARM is going to be most politely described as “anaemic”. ARM chips are not the most powerful (they are the most power-efficient), and x86 code is extremely complicated to emulate. Thus, the overheads of the translation layer are going to sap any hope of reasonable speed.

Internet cameras have hard-coded password that can’t be changed
by Peter Reutemann 08 Jun '17

08 Jun '17

'Security cameras manufactured by China-based Foscam are vulnerable to remote take-over hacks that allow attackers to view video feeds, download stored files, and possibly compromise other devices connected to a local network. That's according to a 12-page report released Wednesday by security firm F-Secure. Researchers at F-Secure documented 18 vulnerabilities that the manufacturer has yet to fix despite being alerted to them several months ago. All of the flaws were confirmed in a camera marketed under the Opticam i5 HD brand. A smaller number of the vulnerabilities were also found in the Foscam C2. The report said the weaknesses are likely to exist in many other camera models Foscam manufactures and sells under other brand names.' -- source: https://arstechnica.com/security/2017/06/internet-cameras-expose-private-vi… Not sure whether these cameras are sold here in NZ...

Ubuntu Works With GNOME To Improve HiDPI Support On Linux Desktop
by Peter Reutemann 07 Jun '17

07 Jun '17

'Canonical is playing host to a 'fractional scaling hackfest' in its Taipei offices this week. Both GNOME developers and Ubuntu developers are in attendance, ready to wrestle with the aim: improve GNOME HiDPI support. Ubuntu's Unity desktop (I'm told, anyhow) plays fairly nice with high DPI monitors because the shell supports fractional scaling (though most apps, I believe, do not). Furthermore, users can tweak some high DPI settings to better suit their display(s). GNOME Shell also supports HiDPI monitors, but has, until now, been a little less flexible about it. "Currently, we only allow to scale windows by integral factors (typically 2). This proves somewhat limiting as there are many systems that are just in between the dpi ranges that are good for scale factor 2, or unscaled," the hackfest page explains.' -- source: https://linux.slashdot.org/story/17/06/06/2048243 Other links regarding HiDPI: http://www.makeuseof.com/tag/linux-hidpi-support-for-gnome-kde-xfce-cinnamo… https://www.maketecheasier.com/best-linux-desktop-environments-for-hidpi-di… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

SGI Desktop Clone Gets A New Version On Fedora
by Peter Reutemann 06 Jun '17

06 Jun '17

'Silicon Graphics workstations used the IRIX Interactive Desktop (formerly called Indigo Magic Desktop) for its IRIX operating system (based on UNIX System V with BSD extensions). "Anyone who remembers working on a SGI machine probably has fond memories of the Magic Desktop for IRIX," remembered one Slashdot reader in 2002. At the time a project called 5Dwm was working on a clone, and its work is still being continued by MaXX Interactive. Today Slashdot reader Daniel Mark shared the news that after "several years and many long nights," the company is announcing a new release for Fedora 25, adding that "more Linux Distributions support will be added over the coming days/weeks." They're calling it "something new and fresh in the Linux Desktop space." The MaXX Desktop is available in two versions, the free Community Edition (CE) which provides basic SGI Desktop experience and the commercially available Professional Edition (PE) that comes with support, CPU and GPU specific optimizations and a full SGI Desktop experience... So there is no surprise here, the MaXX Desktop is a highly tuned Workstation Environment for the Linux x86_64 and ia64 platforms. Multi-core processing, NVidia GPU specific optimizations are among the things that makes the MaXX Desktop so fast, light-weight and stable.

Network Time Protocol Hardened To Protect Users From Spying, Increase Privacy
by Peter Reutemann 05 Jun '17

05 Jun '17

'The Internet Engineering Task Force has taken another small step in protecting everybody's privacy... As the draft proposal explains, the RFCs that define NTP have what amounts to a convenience feature: packets going from client to server have the same set of fields as packets sent from servers to clients... "Populating these fields with accurate information is harmful to privacy of clients because it allows a passive observer to fingerprint clients and track them as they move across networks". The header fields in question are Stratum, Root Delay, Root Dispersion, Reference ID, Reference Timestamp, Origin Timestamp, and Receive Timestamp. The Origin Timestamp and Receive Timestamp offer a handy example or a "particularly severe information leak". Under NTP's spec (RFC 5905), clients copy the server's most recent timestamp into their next request to a server – and that's a boon to a snoop-level watcher. The proposal "proposes backward-compatible updates to the Network Time Protocol to strip unnecessary identifying information from client requests and to improve resilience against blind spoofing of unauthenticated server responses." Specifically, client developers should set those fields to zero.' -- source: https://tech.slashdot.org/story/17/06/03/0422246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

US Supreme Court Victory for the Right to Tinker in Printer Cartridge Case
by Ian Stewart 01 Jun '17

01 Jun '17

"The [US] Supreme Court struck a blow today for your right to own the things you buy, reversing a lower court decision that had given patent owners the power to sue customers who paid in full for a patented item but then used it in a way the patent owner didn't care for. Together with Public Knowledge and R Street, EFF filed an amicus brief at the Supreme Court. We explained that the ability of patent owners to sell products into the stream of commerce while also writing a wishlist of anti-competitive restrictions, would be a disastrous expansion of patent law, hindering competition, innovation, and your freedom to tinker with and repair your own stuff. The Supreme Court agreed, explaining that when a patent owner "chooses to sell an item, that product is no longer within the limits of the monopoly and instead becomes the private individual property of the purchaser, with the rights and benefits that come along with ownership." The Court emphasized that, by default, people have every right to make, sell, and use things. The limited monopoly that the government bestows upon a patent owner is a deviation from the norm of free market competition and ownership of personal property, and is subject to important limits in order to protect the public interest. The Court explained that people who buy things are allowed to use and resell them without being sued under patent and copyright law, and explained that this freedom is necessary for commerce to function. The next logical step will be for courts to recognize that people who buy digital goods are owners of those goods, not mere licensees, and can resell and tinker with their digital goods to the same extent as purchasers of tangible property."

Car Emissions Cheating: How It’s Done
by Lawrence D'Oliveiro 29 May '17

29 May '17

Researchers have been digging through car firmware from Volkswagen and Audi to get to the bottom of the emissions-testing scandal that broke a couple of years ago. Turns out the code was written by Bosch, and important information in the form of “function sheets” (documentation for what the firmware does) was not (officially) forthcoming from that company. But unofficial sources can be found on online forums frequented by vehicle-modding enthusiasts. <https://arstechnica.com/cars/2017/05/volkswagen-bosch-fiat-diesel-emissions…>

Creative Commons Staff Members Release New Free eBook
by Peter Reutemann 28 May '17

28 May '17

'Creative Commons staff-members Sarah Hinchliff Pearson and Paul Stacey have now published Made With Creative Commons, the awaited book they successfully funded on Kickstarter in 2015. "Made With Creative Commons is a book about sharing," explains the book's description. "It is about sharing textbooks, music, data, art, and more. People, organizations, and businesses all over the world are sharing their work using Creative Commons licenses because they want to encourage the public to reuse their works, to copy them, to modify them... But if they are giving their work away to the public for free, how do they make money? "This is the question this book sets out to answer. There are 24 in-depth examples of different ways to sustain what you do when you share your work. And there are lessons, about how to make money but also about what sharing really looks like -- why we do it and what it can bring to the economy and the world. Full of practical advice and inspiring stories, Made with Creative Commons is a book that will show you what it really means to share." There's free versions in PDF, ePub, and MOBI formats for downloading from the Creative Commons site, and there's also an edit-able version on Google Docs. A small Danish non-profit publisher named Ctrl+Alt+Delete Books is also publishing print copies of the book under a Creative Commons license "to ensure easy sharing," and is making the book available on Amazon or through the publisher's own web site.' -- source: https://news.slashdot.org/story/17/05/28/0130259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Timers In systemd
by Lawrence D'Oliveiro 27 May '17

27 May '17

Was referred to this page <https://wiki.gentoo.org/wiki/Systemd> about enabling systemd as the init system in Gentoo. The section on “Timer services” I found particularly useful, as applicable to other distros running systemd: instead of a conventional crontab, you create .timer entries, and corresponding .service descriptions for them to invoke, in your ~/.local/share/systemd/user area. One advantage of this I can see is one less set of user files kept in /var. In fact, do this in conjunction with maildir format for user mail, and you no longer need to have any user files in /var. (That I can think of, anyway...)

Popularity Contests

In the middle of another Phoronix flame war, someone posted links to a couple of interesting pages. What’s your favourite desktop environment? According to this <https://opensource.com/life/15/7/poll-preferred-desktop-environment>, GNOME is number one, with KDE not far behind. One-third of respondents use something else. Arch Linux offers some stats <https://www.archlinux.de/?page=FunStatistics> on popularity of desktop environments and other software among its users. Here GNOME and KDE add up to only about 50%. By the way, it’s clear from the numbers for browsers and text editors in the latter that lots of people use more than one.

A wormable code-execution bug has lurked in Samba for 7 years. Patch now!
by Peter Reutemann 25 May '17

25 May '17

'Maintainers of the Samba networking utility just patched a critical code-execution vulnerability that could pose a severe threat to users until the fix is widely installed. The seven-year-old flaw, indexed as CVE-2017-7494, can be reliably exploited with just one line of code to execute malicious code, as long as a few conditions are met. Those requirements include vulnerable computers that (a) make file- and printer-sharing port 445 reachable on the Internet, (b) configure shared files to have write privileges, and (c) use known or guessable server paths for those files. When those conditions are satisfied, remote attackers can upload any code of their choosing and cause the server to execute it, possibly with unfettered root privileges depending on the vulnerable platform. "All versions of Samba from 3.5.0 onwards are vulnerable to a remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it," Samba maintainers wrote in an advisory published Wednesday. They urged anyone using a vulnerable version to install a patch as soon as possible.' -- source: https://arstechnica.com/security/2017/05/a-wormable-code-execution-bug-has-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Malicious Subtitles Threaten VLC, Kodi and Popcorn Time Users, Researchers Warn
by Peter Reutemann 24 May '17

24 May '17

'Millions of people risk having their devices and systems compromised by malicious subtitles, according to a new research published by security firm Check Point. The threat comes from a previously undocumented vulnerability which affects users of popular streaming software, including Kodi, Popcorn-Time, and VLC. Developers of the applications have already applied fixes and in some cases, working on it. From a report: While most subtitle makers do no harm, it appears that those with malicious intent can exploit these popular streaming applications to penetrate the devices and systems of these users. Researchers from Check Point, who uncovered the problem, describe the subtitle 'attack vector' as the most widespread, easily accessed and zero-resistance vulnerability that has been reported in recent years. "By conducting attacks through subtitles, hackers can take complete control over any device running them. From this point on, the attacker can do whatever he wants with the victim's machine, whether it is a PC, a smart TV, or a mobile device," they write.' -- source: https://it.slashdot.org/story/17/05/24/1329211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Testing Windows Software For Vulns Too Slow? Do It On Linux!
by Lawrence D'Oliveiro 24 May '17

24 May '17

“Distributed, scalable fuzzing on Windows can be challenging and inefficient. This is especially true for endpoint security products, which use complex interconnected components that span across kernel and user space. This often requires spinning up an entire virtualized Windows environment to fuzz them or collect coverage data.” Porting stuff like Windows antivirus tools to Linux lets Ormandy “run the code I’m testing in minimal containers with very little overhead, and easily scale up testing”. Oh, and “I also think Linux has better tools”. <https://www.theregister.co.uk/2017/05/24/whats_got_a_vast_attack_service_an…>

WannaCry Makes an Easy Case For Linux
by Peter Reutemann 23 May '17

23 May '17

'The thing is, WannaCry isn't the first of its kind. In fact, ransomware has been exploiting Windows vulnerabilities for a while. The first known ransomware attack was called "AIDS Trojan" that infected Windows machines back in 1989. This particular ransomware attack switched the autoexec.bat file. This new file counted the amount of times a machine had been booted; when the machine reached a count of 90, all of the filenames on the C drive were encrypted. Windows, of course, isn't the only platform to have been hit by ransomware. In fact, back in 2015, the LinuxEncoder ransomware was discovered. That bit of malicious code, however, only affected servers running the Magento ecommerce solution. The important question here is this: Have their been any ransomware attacks on the Linux desktop? The answer is no. With that in mind, it's pretty easy to draw the conclusion that now would be a great time to start deploying Linux on the desktop. I can already hear the tired arguments. The primary issue: software. I will counter that argument by saying this: Most software has migrated to either Software as a Service (SaaS) or the cloud. The majority of work people do is via a web browser. Chrome, Firefox, Edge, Safari; with few exceptions, SaaS doesn't care. With that in mind, why would you want your employees and staff using a vulnerable system? [...] Imagine, if you will, you have deployed Linux as a desktop OS for your company and those machines work like champs from the day you set them up to the day the hardware finally fails. Doesn't that sound like a win your company could use? If your employees work primarily with SaaS (through web browsers), then there is zero reason keeping you from making the switch to a more reliable, secure platform.' -- source: https://linux.slashdot.org/story/17/05/18/1757205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Android Go will be focused around building a version of Android for phones with less memory, with the System UI and kernel able to run with as little as 512MB of memory. Apps will be optimized for low bandwidth and memory, with a version of Play Store designed for those markets that will highlight these apps. From a report: Another feature of Android Go will be data management. Android Go will let you easily see your data usage, and thanks to carrier integration, it'll also let you top-up with more data right on your device.' -- source: https://hardware.slashdot.org/story/17/05/17/202209 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
